cylindrical shells ...Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis.
about the y-axis.
How I started the problem was I solved the first equation and got [0,4]. And then I used these numbers and plugged it into the shell method.
The equation that I used for the shell method was the first one equation that I listed.
My answer was 853.33pi.
But, it's incorrect. Can someone show me how to setup and solve the problem?
